IMPROVEMENT IN RAILROAD-FROGS.

Specification forming part of Letters Patent No. 180,369, dated July 25, 1876 application filed June 13, 1876.

To all whom it may concern Be it known that 1, DAVID W. PAYNE, of Corning, in the county of Steuben and State of New York, have invented a new and usei'ul lmprovement in Railroad-Frogs; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention is an improvement upon the combination-frog forming-the subject of Letters Patent No. 138,835, and relates to a certain construction and arrangement of parts, as hereinafter described, whereby a frog is produced which has advantages in respect to cheapncss, durability, and facility of handling and repair.

In the accompanying drawing, forming part of this specification, Figure 1- is a top-plan view of the frog. Figs. 2 and 3 are cross-secof cast-steel, and has a thick web or crosssection, as shown in Fig. 3, to enable it to endure the hammering of the car-wheels for a long time without breaking down. As shown in Fig. 3, the point D has a dovetailed base, which is fitted into a corresponding cavity or recess formed in the meeting sides of the filling-pieces G, and its larger end abutting the ends of the track-rails B B. By this constructiomwhen the guard-rails, filling-pieces, and track-rails are secured together by the bolts E, which pass horizontally through them, it is obvious the point I) will be firmly clamped between the filling-pieces G, and prevented alike from lateral and lengthwisemovement.

I do not claim, broadly, a railroad-frog having a detachable point, nor the use of blocks by clamping the point between them, as shown and described.

The above specification of my invention signed by me this 12th day of June, 1876.

DAVID W. PAYNE.
